Summary

Vaultwarden missing authorization check allows Manager-role users to enumerate all collections

Details

Vaultwarden is a Bitwarden-compatible server written in Rust. In version 1.35.4 and earlier, the getorgcollectionsdetails endpoint (GET /api/organizations/{orgid}/collections/details) is missing the hasfullaccess() authorization check that exists on the sibling getorgcollections endpoint. This allows any Manager-role user with accessAll=False and no collection assignments to retrieve the names, UUIDs, user-to-collection mappings, and group-to-collection mappings for all collections in the organization. This issue has been fixed in version 1.35.5.
